In addition to information within the Heritage Center section of the forum concerning Signature Series SSRs, this thread contains "For Sale" information from 2017. @Flassh knows this truck very well.
Lynn and I are thinning down our collection and would like to find the very special Signature 12 a good home. For those that aren't familiar with this truck it is the Gibson Guitar truck and includes the beautiful custom made Gibson guitar. Check out this video for more detailed info on this...
Both @Flassh (Canada) and @Greg Ducato (Weatherford TX) have owned this truck. Not sure who owns it now. Greg was selling it in 2017 but I do not remember is it sold or not.
